To refine your extracts further, we offer premium filter media designed to enhance clarity, remove impurities, and fine-tune the final product. We're your trusted source for the essential supplies that keep your lab running clean, efficient, and compliant.
Chemical Solvents and Filtration Media FAQ:
What types of chemicals does BVV carry for extraction and processing?
BVV stocks a full range of high-purity chemicals built for extraction, laboratory, and industrial processing. Our catalog spans laboratory solvents and alcohols, specialty hydrocarbon blends, compressed and inert gases, filtration and adsorbent media, plus process acids, bases, and performance additives, all sourced for consistent purity and repeatable results.
Which solvents are best for botanical extraction?
The right solvent depends on your process. Ethanol (including USP ethyl alcohol and denatured blends such as CDA-12 with n-heptane) is the standard for cold ethanol and tincture-style extraction, while n-heptane and proprietary blends like BVV™ 710 are used for winterization, washing, and crystallization. Each solvent is offered in high-purity grades with documentation so you can match it to your equipment and target output.
What is the difference between hydrocarbon extraction and ethanol extraction solvents?
Hydrocarbon extraction uses refined gases — primarily butane and propane — that run through a closed-loop system under pressure to pull resins efficiently at low temperatures. Ethanol extraction uses a liquid alcohol solvent, which is simpler to recover and food-friendly but typically requires winterization and additional filtration. Many processors keep both on hand and choose based on the input material and the finished product they're after.
What filtration and adsorbent media does BVV offer?
BVV carries one of the largest selections of filtration media in the industry, including Celite® 545 diatomaceous earth, Pure-Flo® bentonite clays, activated alumina, activated carbon, silica gel, molecular sieves, and ready-to-use prepackaged media cartridges. Each media targets a specific job (decolorizing, dewaxing, moisture control, or polar-compound removal) so you can build a filtration stack around your exact cleanup goals.
What is filtration media used for in extraction?
Filtration and adsorbent media clean, clarify, and stabilize extracts. Diatomaceous earth (Celite) acts as a filter aid that traps plant lipids and fines; bentonite clay and activated carbon decolorize and lighten dark extracts; activated alumina and molecular sieves remove water, acids, and polar impurities from hydrocarbons and solvents. Used together in a column or cartridge, they deliver clearer, more consistent finished product.
How do I choose the right filtration media?
Start with your problem. For dark color, reach for activated carbon or a carbon-and-bentonite blend; for lipids and waxes, use a diatomaceous earth filter aid; for moisture and polar contaminants in butane or ethanol, use activated alumina or molecular sieves. For an easier setup, prepackaged media cartridges combine these adsorbents in pre-measured ratios so you get repeatable filtration without weighing and packing media by hand.
What are refined gases used for, and what purity should I expect?
Refined gases such as instrument-grade butane and propane are the working solvents in closed-loop hydrocarbon extraction, while nitrogen and other inert gases are used to assist filtration, purge systems, and blanket sensitive materials. BVV sources ultra-refined, high-purity gases so you avoid the residual oils and contaminants found in lower-grade fuel-store products.
Are BVV chemicals laboratory or food grade?
Grades vary by product and are listed on each item. Many solvents are offered in USP and high-purity laboratory grades, and several filtration media, including Celite® 545, are Food Chemicals Codex grade and approved as processing aids in the food industry. Always confirm the specific grade on the product page and its accompanying documentation before purchase.
Do your chemicals come with a Certificate of Analysis (COA) and Safety Data Sheet (SDS)?
Yes. Product Data Sheets (PDS), Safety Data Sheets (SDS), and Certificates of Analysis (COA) are available for the chemicals and media in this collection, typically linked in the documents section of each product page. These records support compliance, quality control, and safe handling in your facility.
Are BVV chemicals made in the USA?
Many of BVV's filtration media and chemicals are USA-made and ship with certificates of analysis, including our activated alumina, Celite® 545 diatomaceous earth, and select carbon and clay media. Country of origin and certifications are noted on the individual product pages.
How should extraction solvents and chemicals be stored and handled?
Store flammable solvents and compressed gases in approved containers within a properly ventilated, temperature-controlled area away from ignition sources, and follow the handling and PPE guidance in each product's SDS. Fine powders such as diatomaceous earth should be handled with appropriate respiratory protection to avoid inhalation. When in doubt, defer to the SDS and your local fire and safety codes.
How are flammable solvents and compressed gases shipped?
Flammable solvents and compressed or refined gases are regulated hazmat and ship under DOT requirements, often via ground freight only, with quantity, packaging, and destination restrictions. Bulk media and large containers may also ship by freight and require a forklift or pallet jack for delivery. Shipping method and lead time are noted on the product page; freight items may carry additional handling time.
Who are these chemicals intended for?
This collection is intended for licensed processors, laboratories, and commercial operators who use solvents, gases, and media for legal botanical extraction, refinement, food processing, and analytical workflows. Products should be used by trained personnel in compliance with all applicable federal, state, and local regulations.
